Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of AC frequency converter cooperating equipment, and particularly to an ARM microprocessor operating device for an AC frequency converter. Background Art
[0002] The ARM chip is a microprocessor chip based on the RISC architecture, featuring high performance, low power consumption, and low cost. In the control of frequency converters, the ARM chip can achieve high-speed operation and precise control, support a variety of communication and network protocols, and meet complex application requirements. The AC frequency converter is a speed control device with adjustable output voltage and frequency. The AC frequency converter is actually an inverter. It first converts alternating current into direct current, and then uses electronic components to switch the direct current into alternating current. The AC frequency converter operated by an ARM microprocessor uses data storage and processing and interacts with the upper computer to control the entire AC frequency converter. With the enhancement and improvement of the ARM processing function, more and more companies choose the ARM microprocessor for equipment control.
[0003] In the prior art, both the AC frequency converter and the ARM microprocessor are arranged inside a housing to form an integral control device. One side of the control device is for current input, and the other side is for current output. The output current is directly transmitted to the target device. Some companies will set up a circuit-breaking mechanism on the output line to protect the circuit. When the circuit is abnormal and the current is unstable, the target device will lose the stable power supply, resulting in the direct stop of the running state and actions of the work. As a result, the target device will not be in a normal idle stop state when it stops, which is not conducive to the normal operation of the target device when restarted. There is a need for a device to solve this problem. Moreover, the existing control device housing usually uses the method of wind pressure heat dissipation to drive the hot air inside to be discharged and let the outside air enter. This method can play an effective heat dissipation role when the internal structure is not many. However, when the internal structure is more, the single wind pressure heat dissipation cannot effectively meet the demand for hot air discharge. In this regard, the present invention provides an ARM microprocessor operating device for an AC frequency converter that can provide circuit protection while ensuring the internal heat dissipation effect, so as to solve the above problems.

[0036] In this embodiment, the ventilation component 400 is a structure for ventilating and dissipating heat of electronic components.
[0037] As Figure 1 and Figure 2 As shown in the figure, the ventilation component 400 includes a plurality of support plates 401 fixed to the rear side wall inside the installation shell 1, corner blocks 402 fixed between the bottom of the support plates 401 and the rear side wall inside the installation shell 1, vertical heat sinks 403 fixed to the top of the support plates 401 and evenly distributed, a plurality of horizontal heat sinks 404 fixed between the opposite sides of adjacent two vertical heat sinks 403, a ceramic heat conduction plate 405 fixed between the tops of the corresponding vertical heat sinks 403, four ventilation holes 406 respectively opened on the left and right sides of the installation shell 1, and two heat dissipation fans 407 respectively fixedly installed inside the two ventilation holes 406 on the left side.
[0038] It should be noted that two corner blocks 402 are fixed to the bottom of each support plate 401. The corner blocks 402 can provide good support for the support plate 401. The vertical heat sinks 403 are arranged at equal distances from front to back, so that the air flow can normally flow through the gap between the vertical heat sinks 403 and the horizontal heat sinks 404. The positions of the four ventilation holes 406 correspond to each other in pairs, so that the air flow can flow normally.
[0039] In addition, flow holes for air flow are opened on both sides of the AC inverter main body 7, so that the air inside the AC inverter main body 7 can also be exchanged normally.
[0040] In this embodiment, the water cooling component 500 is a structure for water cooling and temperature reduction.
[0041] As Figure 1 , Figure 3 and Figure 4 shown, the water cooling component 500 includes a ventilation box 501 fixed to the right side of the installation shell 1, a filter mesh plate 502 bolted to the right side of the ventilation box 501, a return pipe 503 fixed to the inner side of the ventilation box 501, heat conduction fins 504 fixed to the outer side of the return pipe 503 and evenly distributed, two porous limiting plates 505 fixed to the inner side of the ventilation box 501, a moisture absorption plate 506 slidably connected between the opposite sides of the two porous limiting plates 505, a water tank 507 fixed to the right side of the installation shell 1, two connecting pipes 508 fixed to the top of the water tank 507, a water pump 509 fixedly installed on the outer side of the connecting pipe 508, a temperature sensor 510 fixedly installed on the top of the water tank 507, and a refrigeration mechanism 511 fixedly installed on the outer side of the water tank 507. The moisture absorption plate can be made of water-absorbing and breathable cotton board.
[0042] Water collecting grooves (5061) are provided at the bottoms of the porous limiting plates 505 and the moisture absorption plate 506, and a water level alarm (5062) is provided below the limiting plates in the water collecting grooves. The front and rear sides of the porous limiting plates on both sides of the moisture absorption plate are connected, and a gap for inserting the moisture absorption plate is left in the middle. The width of the gap is wider at the top and narrower at the bottom. Accelerated ventilation strip holes (5063) are evenly formed in the moisture absorption cotton, and restraint strips (5064) perpendicular to the length direction of the accelerated ventilation strip holes are interspersed among the strip holes. The included angle between the inner side surface of the porous limiting plate and the direction of gravity is less than 10 degrees. The two side surfaces of the moisture absorption plate are in the shape of wavy protrusions, and air ducts (5065) are formed between adjacent wave crests. The wavy protrusions on the same side surface are continuously wavy when viewed from the front left or right of the moisture absorption plate, thus forming a wavy air duct; A lifting belt is fixedly provided on the narrower side end face and / or the top end face of the moisture absorption cotton, or a lifting belt is provided on the porous limiting plate for pulling out the porous limiting plate and the moisture absorption cotton together from the installation shell 1.
[0043] It should be noted that both the left and right sides of the ventilation box 501 are open. The ventilation box 501 is located between the right sides of the two ventilation holes 406 on the right, so that external air can enter the interior of the installation shell 1 through the interior of the ventilation box 501 and the interior of the two ventilation holes 406 on the right. The porous limiting plate 505 is a plate with a plurality of through holes formed on its surface, so that the two porous limiting plates 505 can support the moisture absorption plate 506.
[0044] In addition, the moisture absorption plate 506 is an activated carbon moisture removal plate, which can play a role in removing moisture from the passing air. A replacement hole for taking out the moisture absorption plate 506 is provided at the top or side of the ventilation box 501. A replacement baffle located at the top of the replacement hole is connected to the top of the ventilation box 501 by screws, so that the moisture absorption plate 506 can be moved to the outside through the replacement hole for replacement.
[0045] At the same time, both ends of the return pipe 503 penetrate through both sides of the ventilation box 501 respectively and are fixedly connected to the ends of two connecting pipes 508 respectively, so that the return pipe 503 and the two connecting pipes 508 can form an internally connected pipeline line. Among them, the output directions of the two water pumps 509 are opposite. Specifically, one water pump 509 is used to pump out the cooling water inside the water tank 507, and the other water pump 509 is to transport the cooling water back into the water tank 507 to realize the circulation of the cooling water.
[0046] In addition, the sensor end of the temperature sensor 510 penetrates through the top of the water tank 507 and extends into the water tank 507, and the output end of the refrigeration mechanism 511 penetrates and is fixed on the outside of the water tank 507 and extends into the water tank 507. Among them, the refrigeration mechanism 511 can be an existing general refrigeration device such as a refrigerator or a semiconductor refrigeration chip. When using a semiconductor refrigeration chip, it is necessary to ensure that the hot end of the semiconductor refrigeration chip faces outward, and a corresponding heat dissipation and cooling mechanism is additionally provided at the hot end to ensure the normal working state of the semiconductor refrigeration chip. The cold end surface of the semiconductor refrigeration chip can use a rod with good heat conduction ability to extend into the water tank 507 to cool the cooling water inside the water tank 507. Under the real-time monitoring of the temperature sensor 510, the temperature of the cooling water inside the water tank 507 is kept within a preset temperature range.
[0047] In this embodiment, the wiring assembly 3 is a structure for enabling various cables inside the device to have a laying space.
[0048] As Figure 1 shown, the wiring assembly 3 includes a box body fixed to the rear side wall inside the installation shell 1. The front of the box body is open. An inlet hole is provided at the bottom of the box body, a communication hole is provided on the right side of the box body, and a transparent panel is connected to the front of the box body by screws.
[0049] It should be noted that the box body is located between the relative sides of the AC frequency converter main body 7 and the support plate 401. The ARM microprocessor main body 8 and the abnormal protection module 9 can be arranged relative to the top of the ceramic heat conduction plate 405, so that the cables can be conveniently laid inside the box body. Among them, the fronts of the inlet hole and the communication hole are both open, so that the cables can enter conveniently.
[0050] The working principle of the above embodiment is as follows:
[0051] (1) When protecting an abnormal circuit, the current passing through the line can be monitored in real time through the current detection sensor 901. When an abnormality is detected, a signal is output to the controller 902. At the same time, the line is retested through the current detection sensor 901. When the result of the second retest is also abnormal, the controller 902 controls the line switch 1 903 to close and opens the line switch 2 904, so that the output current of the backup power supply 905 can be directly supplied to the output device, allowing the output device to have a certain buffer adjustment time.
[0052] (2) During the operation of various electrical equipment, a certain amount of heat is generated. The water pump 509 and the refrigeration mechanism 511 are started, so that the cooling water in the water tank 507 is cooled and enters the inner part of the round-shaped pipe 503 through the connecting pipe 508 on one side, and then returns to the inner part of the water tank 507 through the connecting pipe 508 on the other side, completing the circulation of the cooling water. The cooling water in the round-shaped pipe 503 can exchange heat with the surrounding air under the heat dissipation effect of the heat conductive sheet 504. The heat dissipation fan 407 is started, so that the outside air is filtered through the filter screen 502 and enters the ventilation box 507. 01, and then heat exchange is performed with the outer sides of the meandering duct 503 and the heat conducting sheet 504, so that the airflow can be cooled down. The cooled airflow absorbs moisture through the moisture absorbing plate 506 and then enters the interior of the installation shell 1. Under the cooperative heat conduction effect between the vertical heat sink 403, the horizontal heat sink 404 and the ceramic heat conducting plate 405, the air inside the installation shell 1 can be cooled down and the hot air can be discharged through the left ventilation hole 406 under the promotion of the airflow, so that efficient heat dissipation effect can be guaranteed, and good heat dissipation and cooling effect can be achieved even when there are many devices installed inside.
[0053] Of course, the support plate, corner block, vertical heat sink, horizontal heat sink, and ceramic heat conductive plate can also be arranged on the left side or back of the AC inverter body 7, and the right sides of the support plate, vertical heat sink, horizontal heat sink, and ceramic heat conductive plate are in contact with or fixed to the AC inverter body 7, thereby improving the heat dissipation efficiency. The cold air generated by the water cooling component 500 can take away the heat of the AC inverter body 7 and the heat on the vertical heat sink, horizontal heat sink, and ceramic heat conductive plate from right to left, and can also speed up the rapid conduction of the heat of the AC inverter body 7 to the horizontal heat sink and the ceramic heat conductive plate.
[0054] In addition, a dedicated elastic flexible material for heat conduction can be provided between the support plate, the horizontal heat sink, the ceramic heat conduction plate and the main body 7 of the AC frequency converter. Such elastic flexible materials can be heat conduction pads, soft silicone sheets, heat conduction rubber pads, etc., so that the support plate, the corner block, the vertical heat sink, the horizontal heat sink, the ceramic heat conduction plate and the main body 7 of the AC frequency converter can be separately and independently installed, and can be connected by extrusion through the above-mentioned elastic flexible materials, reducing the installation difficulty and eliminating the need for the main body 7 of the AC frequency converter to be fixedly connected to the above-mentioned components, thus being adaptable to AC frequency converter main bodies of various models.
[0055] Compared with the prior art, the AC frequency converter uses an ARM microprocessor to operate the device. Through the coordinated use of the current detection sensor 901, the controller 902, the line switch 903, the line switch 904 and the standby power supply 905 inside the abnormal protection module 9, abnormal current can be detected by the current detection sensor 901, and then the controller 902 can be used to control the disconnection or opening of the line switch 903 and the line switch 904, so that the standby power supply 905 can be used when the current is abnormal to enable the target device to complete the ongoing operation, so that the target device will not stop directly when the main power supply has an abnormal phenomenon resulting in unstable current, giving the target device a buffer adjustment time. Through the coordinated use of the ventilation component 400 and the water cooling component 500, and by the combined action of the vertical heat sink 403, the horizontal heat sink 404 and the ceramic heat conduction plate 405, the overcurrent air can take away the heat outside the vertical heat sink 403, the horizontal heat sink 404 and the ceramic heat conduction plate 405. Through the combined use of the refrigeration mechanism 511, the return pipe 503, the heat conduction sheet 504 and the connecting pipe 508, cooling water with a temperature lower than the external environment can flow inside the return pipe 503, and then the heat conduction sheet 504 can efficiently complete the heat exchange work, so that the cooling air flow entering the device can be lower than the ambient temperature, achieving a good heat dissipation and cooling effect, thus ensuring the heat dissipation effect inside the device, and solving the problems that when the existing ARM microprocessor controls the AC frequency converter to output current, it cannot meet the requirement of giving the target device a certain buffer adjustment time when the power supply is disconnected, and when there are too many set structures, the conventional air pressure heat dissipation cannot effectively meet the heat dissipation requirements.
